ELECTRODE SELECTION GUIDE

The number which follows each material is the RWMA (Resistance Welder Manufacturers' Association) number of the electrode which would normally be placed against that material. For Example, when welding Alumel to Consil, a RWMA -2 electrode should be used on the Alumel side, and a RWMA -11 on the Consil side. Not all combinations have been tried successfully.

AboutUs

Advanced Integrated Technologies is essentially a manufacturing service company with two major divisions. The resistance welding and reflow soldering tool division grew out of our early work building micro tools for Hughes Aircraft. About the time that Microsoft was turning computers into a household item, computer hardware manufacturers were looking for companies to build reflow tools used in the assembly of hard drives and other components. The major players like Seagate found A.I.T. and we quickly grew into the industry leader, building more reflow tools and resistance welding electrodes than any other single manufacturer. We still hold that position today.
